Thanks for your interest in Google's Matter Private Beta Program! This program provides early access to the Google Play Services Matter APIs, which allow you to commission and set up Matter devices in Google Home. To determine eligibility, tell us about your plans for Matter.
IMPORTANT: Requests are evaluated on a case-by-case basis. Upon acceptance to the program, you’ll be required to sign a non-disclosure agreement (NDA).
If you're unable to join the Private Beta Program, don't worry, you can start using Google Play Services Matter APIs later this year as part of the public beta.
